How do I get AUB?
The number of elements in A union B can be calculated by counting the elements in A and B and taking the elements that are common only once. The formula for the number of elements in A union B is n(A U B) = n(A) + n(B) – n(A ∩ B).
What does U and upside down U mean?
These are used in set notation. U stands for union. And upside down U stands for intersection.. .For example given the set A = {1, 2, 3} and B = {3, 4, 5} Then A U B = {1, 2, 3, 4, 5} and A intersection B = { 3 }

What does U mean in set?
A universal set (usually denoted by U) is a set which has elements of all the related sets, without any repetition of elements. Say if A and B are two sets, such as A = {1,2,3} and B = {1,a,b,c}, then the universal set associated with these two sets is given by U = {1,2,3,a,b,c}.
